No Idea of how to prove a negative?

If the Acorn employees did nothing wrong, why did Bertha fire them?
Wouldn't it be bad behavior to fire somebody that is courageously helping poor people and did nothing wrong?

How do you know what "the people who made the tapes" wants you to think?

Who is included in people "on their side of the argument"? Am I somehow responsible for what Rush Limbaugh says and am I somehow obligated to condemn or defend it?

Who is included in us? Are you speaking for some sort of group that I am supposed to show a tape to that I don't have?

Is this some sort of hypothetical battle between two opposing sides? A straw man argument?

I am only one person and I am not uncivilly, shrilly calling anybody an asshole because they disagree with me. I invite all points of view. I merely ask that you follow the requirements you place on others.

Remember the dark ages when people thought everything they saw was not real, just the work of demons? You know what you saw but you prefer to demonize some sort of straw man group of people rather that face reality.

If there is any evidence that those tapes were altered somehow, I would like to hear it instead of calling someone an asshole because they ask for proof like you do. The burden is on the accuser, not the accused.
